A roadbed is the bottom part of a road, which provides support for the roadway above it. It typically includes layers of material designed to carry traffic loads and ensure stability and drainage. The roadbed is foundational in road construction, influencing the longevity and performance of the road itself. It must be designed to withstand environmental conditions and regular wear and tear caused by vehicles.

Word origin
The term 'roadbed' originates from Middle English, where 'road' developed from the Old English 'rad', referring to a journey or course of travel, and 'bed' derives from the Old English 'bedda', meaning a prepared place for rest. As road construction evolved in the 19th century, particularly with the advent of engineered road systems, the concept of a supportive structure upon which roads could be built became crucial. The combination of these two elements—road and bed—came together to describe the physical and foundational layer for roadways. This terminology became more prevalent as civil engineering advanced, emphasizing the importance of substructures in infrastructure development.
